What does solar panel installation (complete) cost in 2026?

A complete installation costs on average € 4,000 to € 12,000, mainly depending on the number of panels. Expanding an existing installation costs € 1,500 to € 4,000, replacing an inverter € 800-2,000 and preparing a home-battery connection € 350-900. The roof type, cable route and inverter choice determine where you land in the band.

The net-metering scheme is being phased out and some energy suppliers charge fees for electricity fed back to the grid. That makes self-consumption more important: the more of your generation you use directly, the better the sums work out. Panels still pay off, but the payback period differs per situation — have the installer run the numbers on your consumption and roof rather than a rule of thumb.

Yes. On a flat roof the panels sit in ballast frames held in place by weight, without piercing the roof. You choose the tilt angle yourself and an east-west layout often uses the surface best. On a pitched roof the panels go on hooks and rails under the tiles. You state the roof type in the request, so the quote is right straight away.

That depends on your yearly consumption, the available roof surface and the roof's orientation. In the request, state roughly how many panels you want — or choose 'advice wanted', and the installer will calculate it based on your consumption and your roof.

Yes. Submitting a request costs nothing and commits you to nothing. You receive up to 3 quotes and choose yourself — or no one, that's fine too. Prices and payment are arranged directly with the installer.

Installers in your region respond as soon as possible with a price indication or quote. Solar panels are a planned job: from request to installation, allow a few weeks depending on demand and material delivery times — spring is the busiest season.

Yes. We verify Chamber of Commerce registration when a company joins and ask for proof of business liability insurance. Panel mounting and fuse-box work are skilled trades: the affiliated companies are installation firms that do this daily.

Your details are shared only with the (up to 3) installers matched to your request. We never resell your data and automatically delete requests after the legal retention period. See our privacy policy.

For most homes, no: panels on your own roof are generally permit-free. For listed buildings and in protected cityscapes rules do apply — check with your municipality beforehand. The installer knows the local situation and thinks along about what is possible on your roof.

Schemes and VAT rates change and differ for consumers and businesses. We therefore deliberately mention no amounts or schemes here: check the current information with the national government and the tax authority, and ask the installer in your quote what applies right now.

No — cleaning and bird-proofing fall outside this site. For those, see our sister site Zonnepaneelhulp (zonnepaneelhulp.nl), where you compare cleaners and maintenance specialists. Here everything is about installation: new systems, expansions and inverters.

Installing the home battery itself runs via our sister site Thuisaccu Direct (thuisaccu-direct.nl). What you can do here: prepare the connection — a battery-ready inverter, a free circuit and the cabling — so the battery can be added later without breaking anything open.
